To all whom, it may concerm' Beit known that I, CHARLES MARWITZ, of Oak Park,"in""the county'of Cook and State of Illinois, have invented certain new and use.- ful Improvements in Milk-0an Washers, ot'l This invention relates to improvements 'inn milk-can scrubbers or washers, and refers more specifically to a portable device adapted to be conveniently transferred from can tol 'Among the objects of the invention are to provide a construction in which the brush members of each can be readily folded, so as to permit their ready insertion and removal; to provide means for automatically locking same time permitting the necessary manipulation of the brushes toinsure their reachingall parts of the interior of the can; to provide a simple mechanism for automatically cenv tering the brushes within thecan, combined with means for locking the apparatus positively to the can-body during operation; to provide a simple gear mechanism whereby the brushes may be driven at a relatively high speed, and in general to provide a simple, re-

device of the character referred to. i

The invention consists in the matters hereinafter described,and more particularly pointed ont in the appended claims, and the same will be readily understood from the following description, reference being had tothe accompanying drawings, in which- 4 Figure 1 is a side realevation,l with parts showuin axial section, ol a preferred embodiment of my invention shown as applied to a milk-can of the usual construction, the latter being shown in axial section. Fig..2 is a plan View of the base-plaie, showing more parmechanisnn, all other parts being omitted. Fig. 3 is asectional view taken ou line 3 3 of Fig. 1; and looking downwardly, the relative position of the driving-pinion being indicated in dotted lines and the brushes being re- Referringto said drawings, A designates asa wholean ordinary milk-canhaving the usual outwardly-flaring mouth or neck a and B 'designates a baseplate having' the forni of a sheet-metal disk somewhat larger than the mouth of the milk-can and provided at'its under side with aconical downwardly-extend- Y ing flange-b', adapted to enter the mouth of the milk-can, said flange being considerably deeper than the depth of the flaring portion what smaller dimensions as wellas in the can shown. vIn order that said base-plate andthe mechanism mounted thereon maybe clamped securely. to the-mouth .of .the milk-can, a clamping mechanism is provided, consisting of a clamping-lever b', pivoted between. its

`ends at a point a short distance fromthe center of the disk, as indicated at b2, and arranged to extend.approximately radially out' ward some distance beyond the margin of the plate to form a handle. At points equidistant from the pivot h2 clamping-arms b3 b4, respectively, are' pivotally connected with' said lever and arranged to extend oppositely out through suitable guide-openings b5 in the,

flange b, the outer ends of said clampingarms being `formed into downturned hooks b, i

the clamping-lever is. oscillated so as to retract said arms. In order to lock the clamping mechanism in clamped position, the outer end of the clamping-lever, which is of strap met-al, is returned upon itself, as indicated at (i7, and arrangedto overlie the upper periphery of. the base-plate, while -the latter-is provided with a series of locking-aperturesA` ha, arranged at intervals apart concentrically with the pivot b and adapted to receive a downwardlyprojecting stud b,I mounted return portion hl of the clamping- Upon the base-plate B is ,mounted a sup'- porting-frame comprising` two nlainupright members O C', the former of which is oon- .veniently made in the `form of a casting hav- `adapted to engage the bead a of the can when v i ing diverging side members c, converging to-V gether at their upperends and united' at their lower ends and at, two'intermediate points by means of cross-bars c' c2 c, respectively.v The member C may conveniently be simply a rod or bar provided at itsfupper end with a hoi-izontal'portion c" and a vertical portion c5, the, lower end of which is providedwith a foot c,

IOO

. sition to intermesh with the with a suitable handle E',

therewith, whereby it may be driven man-l suitably bolted to the base-plate; it b eing understood that, as shown in the drawings, the frame member C' will be arranged at right angles to the plane of the casting C, so that said frame as a whole has a triangular base;

Between the cross-bars c' c2 is arranged a horizontally-disposed pinion D, the hub d of which is provided with trunnions orjournals d d2, respectively, engaged with suitable journal -apertures formedl in the said cross members c c2. y

E designates a dri ving-gear mounted in posuitable bearing-stud e, which projects outwardly from the cross-har csof the frame member c. The driving-gear E 'is provided rigidly connected ually, said handle being bent or deflected outwardly to avoid interference with the baseplate, as indicated clearly in the drawings.

Describing now the brushes and their driving connection with the gear mechanism hereinbefore described, F F designate two skeleton frames conveniently having the form of metal bars and each frame suitably shaped to conform approximately to the internal conformation of one vertical half of the can. Said brush-frames are arranged to meet at their upper and lower ends upon the axial line of the can and are 'each provided at said meeting ends with laterally-odset overlapping pivot-ears f j", through which are inserted pivot-bolts f2 f, the arrangement of these 3y oflse-t ears and pivot-bolts being such that upon each other, as

the brush members maybe folded together indicated at Fig. 3. Upon the brush-frames F and F' are mounted a series of brushes F2, adaptedto reach all parts of the interior of the body of the can,

'and in order that the weight of the. brushes and brush-frames'may not rest upon the bris tles or brushA of the lowerendbrushes the pivot-bolt f 'i is-extended downwardly to form a supporting-studf2which supports the frame by resting in contact with the bottom of the can.

Each bruslpframe is as F3 F4, respectively, form in cross-section throughout the intermediate portion of its length, the pivotal arrangement of said brush-frames being such that when the brush-frames are opened out into alinementwith each othcrthe said Shanks will be brought together and will in' practical edect form a single shank of rectangular cross-section. The pinion D is provided with a correspondin gaxiall y-arran ged rectangular aperture d3, adapted to receivesaid shanks when thus folded togethemas indicated clearly in Fig. 1. The shank FLis arranged to extend upwardly beyond the pinion through suitable bearing-apertures formed in the upper ends of the frame members C C', that portion of; said shank extending through the frame members being made round and of uniprovided with a shank,

pinion D upon a' `ruptly enlargedA to of oblong rectangular' time it approaches,

form diameter for some distance above and below its engagement with said frame inembers, so as to enable tliebrushes-to be rotated freely and at the same time lifted up and down to accommodate cans of different height interiorly. In order to facilitate such masaid shankF is provided-With a handle f5; rotatably journaled thereon and secured in position by a suitable key f6. The shank Fs is made to terminate at a short distaceabove the pinion D, whilethe angular port-ion of the shank 'F4 above the end of the shank F3 is abthe same cross-sctional size and. shape as the pinion-aperture, so that when the base-plate is released from the can the frame and gear mechanism may be lifted bodily upward until the pinion passes out of engagement with the shank F, while the brushes remain in position within the can.

nipnlation of the brushes, the upper end of' rsv The operation'of the device may be briefly u described as follows: The base-plate and gea-r mechanism mounted thereon being lifted upwardly relatively to the brush-frames, so' that the pinion engages the enlarged angular part l f7 of the shank F4, the'brush-frames may be folded together, so as to permit their ready insertion within the can. After the brushes have been inserted within the can a partial rotation of the frame relatively to the can will result in opening out thebrnshe's into alinement with each other,- Whereupon the Shanks being thus brought together the pinio`n-D and connected parts will. be free to slide downward ly upon the shanks until the basefan b of the base-plate rests within the da part of the mouth of the can. The .base-plate A is nowloeked to the rim of the can-mouth by means of the clampingmechanism, and -thedevice is in readiness for operation. In eperating the device the other he lifts the brushes-iup andy down (in case this be required) luntil the can\is the operator simply turns. the driving-gear with one hand, while with" brushed or scrubbed clean, -it being'une-l stood that the can has been partly lled with suitable cleaningjlnid.- The withdrawal lout the apparatus is obviouslythe exact reverse operation from that t-o the can. l

From the foregoing description it will be seen that the objects of the invention are fully attained by the apparatus described and a simple practical and durable machine profl duced which' may be manufactured and soldl at a com paratively-small price, .thus enabling dealers who use but a small number of cans to alord the'apparatus, while at the same if not equals, in capacity and elliciency machines which have heretofore been operated. by power.

While the present construction is deemed. a preferred and practical embodiment-of my' invention, yet it will be understood that the details thereof described in applying it izo may be somewhat modi-fied without departingfrom the invention. L do esatti'i :i

not therefore wish to he limited to the details shown, except as madethe subject of specific claims.
